Western & Central Mass Weather Outlook For The Month Of July

Unfortunately, current data points to the potential for the current wet weather pattern to persist through the month of July. The average upper level weather pattern across the United States during the month of July looks to consist of a big high pressure system over the Rocky Mountains into the southwestern United States and upper level trough of low pressure over the eastern and in particular the northeastern United States. This looks to translate to a surface weather pattern of fairly frequent frontal systems moving through on average every 3 to 4 days or so. So while there will be sunshine, there will also be fairly frequent bouts of showers and thunderstorms during July. Temperature: I’m forecasting temperatures that should be about average for a typical July. This means plenty of 80-plus degree days and nighttime low temperatures between 55 and 65 Degrees. While a 90-plus Degree day or two or three is likely during July, I think this July will not even be close to being as hot as last July. If we’re going to have any extended hot weather, it would be near the end of July. Rainfall: I’m forecasting above average rainfall for the month of July. In terms of amounts, my thinking is for rain totals in the neighborhood of between 5 and 7 inches across the region. This is about 2 inches above average. In the next couple of weeks or so, I am watching two time periods for heavy rain - The first is this coming Sunday night into Monday when widespread heavy showers could deposit 1 to 2 inches of rainfall across the entire area. The second time period that I’m watching is the period between July 8 and July 10 when another round of heavy rain that could put down 1 to 3 inches of rain across the area.

Western & Central Mass Forecast For The Weekend & The Fourth Of July

The last of the thunderstorms is about to exit Central Mass and we'll be left with a quiet night and a quiet, but warm and humid couple of days across the entire area.

Generally cloudy skies with perhaps some breaks in the clouds are expected Tonight. Low temperatures will be between 60 and 65 Degrees.

Thursday & Friday both look like quiet days under partly sunny skies on Thursday and sunny to partly sunny skies on Friday. High temperatures will be between 80 and 85 Degrees on Thursday. High temperatures Friday will be near 85 Degrees. In terms of humidity, Thursday looks like a humid day, but lower humidity levels look likely for Friday.

Turning To This Weekend: Current indications point towards Saturday being the better weather day and Sunday looking quite unsettled.

Saturday looks like it’ll feature a mixture of sunshine and clouds with high temperatures near 80 Degrees.

A frontal boundary is forecast to push through the area during the day on Sunday. In addition, a wave of low pressure may try to form along this front, which could enhance the rainfall. This all means that I expect widespread showers and scattered thunderstorms during Sunday, especially in the afternoon. It will be very humid with high temperatures near 75 Degrees.

Looking Towards The Fourth Of July - It appears that scattered showers will persist into at least part of Monday with the Fourth of July still looking dry under partly sunny skies. High temperatures Monday will be between 80 and 85 Degrees. High temperatures for the Fourth of July will be between 80 and 85 Degrees. Unfortunately, both days also look humid.

A Line Of Thunderstorms, Some Strong, Will Move Eastward Into Central Mass Next Couple Of Hours

A line of thunderstorms, some strong in intensity are now pushing eastward across the I-91 corridor as of the time of this writing.

These storms are moving eastward at a forward speed of about 15-20 mph.

I anticipate that this line of thunderstorms will reach areas around Monson and Palmer by about 5:30-5:45 pm and then reach areas around Sturbridge, Brookfield and New Braintree by about 6-6:15 pm or so.

Areas around the Worcester Metro and the I-395, I-190 and Route 146 corridors are currently anticipated to see this line of thunderstorms by about 7 pm.

These thunderstorms will contain heavy downpours and frequent lightning. Additionally, some of the stronger storms will be capable of producing wind gusts of 40-50 mph and pea size hail.
